ARTHUR Donn-rive, or SIEBENBRUNN, GERMANY PEDAL PROTECTOR I '1 This invention relates to pedal protectors especially for use on the pedals of musical instruments. It is an improvement on the kind of protectors at present in use, such 5 as consist of a pocket of india rubber or the like adapted to be drawn over the pedal in the manner of a sock.

It is known that the hitherto used pedal protectors easil slip from the pedals over which they are rawn, so that the player frequently has to return them into their proper position. This drawback is apparent even in connection with sharply bent pedals, which likewise give Way under the continuous strain to which they are subjected by the players feet, and it was not possible, hitherto, to remove this discrepancy by using tightly fitting protectors. Besides, it is extremely diflicult to slip a tight fitting protector over a pedal and there is always a risk of its bursting to be feared.

The invention, therefore, solves the problem in a different way and provides an indiarubber or the like protector, which may be easily drawn onto the pedal and find a firm hold thereon without the risk of its slipping back While being subjected to the work of the players feet.

To achieve this object the invention provides for a protector of such shape which, when applied, will cause a partial vacuum in the hollow pocket of the protector and maintain such under all conditions of work and rest. The said partial vacuum or rarefication of the air causes the protector to cling to the pedal not by its own quickly relaxing pressure or elasticity, but by atmospheric pressure, so that the vexatious slipping of the protectors can no more take place.

According to the invention the protector is provided at its opening with a thickened retraction formin a suction lip which closes tightly all aroun vides that the air, which has been forced out of the pocket during its application and contraction over the pedal, will not be able to return. Thus the partial vacuum which has formed in the interior of the protector 5 remains constant so that the atmospheric the pedal and thus pro- Application filed December 13, 1828, Serial No. 325,712, and in Germany-February 13, 1928.

pressure acting from without secures a permanent grip of the protector upon the pedal.

Since the only resistance to overcome is that of drawing the tight suction lip over the pedal when applying the protector, and as otherwise the pocket of the latter is sufficiently wide, it is evident, that this Work can easily be carried ,out by persons who are not of great physical strength.

The accompanying drawing illustrates the invention by way of example.

Fig. l is a longitudinal section, and

Fig. 2 a plan view, of an improved protector for use on piano pedals.

As will be seen the pedal protector b which complies in its form to the shape of a piano pedal and which has a serrated or non-skid upper surface a is provided at its slip-011 end with a thick suction lip or rim at bordering the opening all around, and with a contraction g at the mouth of the pocket or chamber h, by which means it is able to firmly grip the pedal after having been drawn over the same. The width of the pocket is chosen so as to be slightly greater than that of the pedal to which the protector is to be applied,'so that the latter will be able to slip just easily onto the pedal after the suction lip d has been brought over it.

I What I claimis 1. A protector for the pedals of musical instruments and comprising a pocket adapted to be drawn over the pedal, having the interior of its pocket slightly larger than the width of the pedal over which it is to be drawn, and a contracted slip-on opening.

2. A protector for the pedals of musical instruments consisting of a pocket adapted to be drawn over the pedal, having the interior of its pocket larger than the width of the pedal, and having a thickened suction lip at its slip-on end.

3. In a protector for the pedals of musical instruments, a pocket approximately to comply to the shape of the pedal, the interior of the said pocket being of a width slightly larger than that of the pedal, a contracted slip-011 opening to the said pocket of a width smaller than the thickness of the pedal, and

a thickened rim bordering the opening all round.

4. As a new article of manufacture, a protector for the pedals of musical instruments consisting of an india-rubber pocket having a roughened upper surface, a contracted slip-on opening of a Width smallerthan the thickness of the pedal, and a thickened rim bordering the said opening all round, the interior of said pocket being of slightly larger width than the pedal which is to be covered therewith.

In Witness whereof I afiix my signature.
